Will it hurt my Cadillac DTS to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What should I do if I see leaks under my DTS?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my DTS engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Where can I get a tune-up for my Cadillac DTS?

How often should I clean my Cadillac DTS fuel injectors?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune Into Your Cadillac DTS

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you drive a 2008 Cadillac DTS. Periodic tune-ups can bring more power back to your DTS’s engine. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Cadillac for your vehicle’s tune-up schedule, you invest in your DTS's long-term health and engine performance.

Engine Tune-Up for Cadillac DTS

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2008 Cadillac DTS. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your DTS. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your DTS’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your DTS: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Cadillac DTS Tune-Up
